Greater Manchester Police chief constable Sir Peter Fahy has been served with a criminal and gross misconduct notice in relation to his "alleged support to an allegedly poorly-handled investigation into a suspected sex offender", the Independent Police Complaints Commission (IPCC) has said.
Another serving officer has been handed a gross misconduct notice following the investigations - prompted by allegations made by a whistleblower - for his oversight in the disposal of body parts belonging to victims of serial killer Harold Shipman.
The IPCC inquiry was broken down into three investigations - claims concerning Shipman's victims, allegations against a detective chief inspector, and claims concerning a sexual abuse investigation.
Sir Peter, a detective superintendent and a detective chief inspector, all serving, have been handed criminal and gross misconduct notices in relation to the investigation into the suspected sex offender. A retired officer will also be served with a criminal and gross misconduct notice over his role in this investigation.
